01 · Know the question

Decide what evidence would answer it.

A topic tells you where to look. A research question tells you what relationship the literature must explain. Before opening a database, define the constructs, population, boundary conditions and outcome—then translate them into searchable concept blocks (Bramer et al., 2018; Aromataris & Riitano, 2014).

Fictional honours question

Among university students, how do the timing and intensity of simulated moonlight exposure before sleep influence next-morning memory performance?

The wording already sketches the argument: an exposure may change an outcome, and two boundary conditions may explain when the effect changes direction.

01Who?University students

Population · useful for judging relevance; often optional in the first search.

Translate—do not paste

A database searches words, not your argument.

Keep concept nouns and their synonyms. Usually leave out question words and relationship verbs such as how, whether, effect and influence. They describe the reasoning task but rarely retrieve the evidence efficiently.

The study-by-study trap

A chronology is not yet an argument.

Nguyen and Bell found X. Okafor and colleagues found Y. Silva and Park found Z.

The reader has to infer the relationship between findings. Reviews organised around authors tend to conceal the concepts and debates that matter (Webster & Watson, 2002).

The synthesis move

Organise around a contestable claim.

Evening cool light does not have a uniform effect on memory; its influence appears to shift with timing, intensity and sleeper characteristics.

The sentence names the pattern; citations supply the evidence. This concept-centred structure enables analysis of themes, gaps and disagreement (Monash University, n.d.).

Narrow the question one paragraph at a time.

An introduction is not a funnel because it moves from “broad” to “specific” in a vague way. It is a funnel because each paragraph removes one uncertainty until your study becomes the logical next step.

Research basis

This six-paragraph teaching sequence expands the CARS model: establish the research territory, establish a niche, then occupy that niche with the present study (Swales & Feak, 2012). The exact number of paragraphs varies by discipline; the rhetorical moves matter more than the count (Purdue Writing Lab, 2024).

Practice 6 of 7

Build the introduction’s spine.

Arrange these mini-paragraphs so each one creates the need for the next.

Sentence 1
Research suggests that cool light can either impair or support memory depending on its timing and intensity.
Sentence 2
Memory is stabilised during sleep, making the period before sleep important for learning.
Sentence 3
The present study therefore tests their independent and combined effects, predicting a benefit of dim light at dusk but an impairment from bright light immediately before sleep.
Sentence 4
Evening light may alter this process by changing alertness and subsequent sleep depth.
Sentence 5
Yet timing and intensity have not been tested together, so the source of these divergent effects remains uncertain.

Full worked example

A complete introduction, stopping before Method

Fictional model · 6 paragraphs

New memories remain fragile until they are stabilised, a process that continues during sleep (Delgado & Morris, 2020). Conditions in the period before sleep may therefore influence how effectively recently learned material is retained. Light is one such condition: it shapes alertness before sleep and may also alter the sleep processes that support memory consolidation (Nguyen & Bell, 2021; Rao & Ellis, 2023). Understanding this relationship matters in environments where evening light exposure is common but learning must be retained.

Cool-spectrum light is especially relevant because it may increase alertness while also delaying the transition to deeper sleep (Nguyen & Bell, 2021; Rao & Ellis, 2023). These effects imply competing pathways. Increased alertness during encoding could strengthen an initial memory trace, whereas disrupted sleep could weaken its later consolidation. The influence of cool light should therefore depend not only on whether it is present, but also on when it is delivered and at what intensity.

Evidence from late, bright exposure is broadly consistent with a disruptive pathway. Bright cool light immediately before sleep has been associated with poorer word recall following reduced deep sleep (Nguyen & Bell, 2021). Similarly, simulated moonlight impaired spatial recall among poorer sleepers, who may be especially vulnerable to further sleep disruption (Karim, 2025). Together, these findings suggest that intense light close to sleep can undermine memory, although the effect may vary between individuals.

However, lower-intensity exposure earlier in the evening may produce a different pattern. Dim cool light at dusk improved image recall relative to darkness (Okafor et al., 2022), whereas warm light produced no comparable memory change (Rao & Ellis, 2023). Crucially, the benefit of cool light was present at dusk but absent immediately before sleep (Silva & Park, 2024). The literature therefore points to timing and intensity as boundary conditions that could explain why cool light has appeared both beneficial and harmful.

Existing studies have typically varied timing or intensity in isolation (Nguyen & Bell, 2021; Okafor et al., 2022; Silva & Park, 2024). As a result, it is not known whether dim and bright cool light have different effects at dusk and immediately before sleep, or whether one factor dominates the other. Testing both factors within one design would distinguish a general effect of cool light from an interaction between its timing and intensity.

The present study therefore aims to determine the independent and combined effects of cool-light timing and intensity on next-morning word recall. It is hypothesised that (H1) dim cool light presented at dusk will improve recall relative to darkness; (H2) bright cool light presented immediately before sleep will impair recall relative to darkness; and (H3) timing and intensity will interact, such that the most favourable recall will follow dim dusk exposure and the poorest recall will follow bright pre-sleep exposure.

StopThe Method begins after this point.

No sampling, materials or procedure are needed to justify the argument.
